sn0mm1s and any others. Back to whale evolution for a bit, as it was brought up earlier in the thread and I unfortunately have been too busy to get to it.
Pakicetus is the first fossil I've researched. When it was first discovered, the skull and portions of the mandible were discovered in coastal regions of Pakistan (thus the name). It was immediately hyped as a whale ancestor, and Science magazine put it on the cover:

So for years, Pakicetus was used as a great example of evolution. But as you see here, there was no science involved. What happened was no different than if I found 50 pages of Gone with the Wind and attempted to write the story around it. It's artistic and it's speculative, but its not science.
In 2001, more remains were found. Quickly, it was learned that the pakicetus looked nothing at all like the pictures that had been in people's brains for years. Now it's clear that the animal looked a lot like a dog or a wolf. In fact, it was written by one of the scientists involved that it was a "terrestrial mammal, no more amphibious than a tapir". This same scientist though, argued in 2009 that one reason it could still be argued as a whale ancestor is that it had heavy bones and orbits that were close together on the skull, indicative of aquatic animals that live in water and look at emerged objects.
The artistic renderings that were given to pakicetus are still used inaccurately and give false delusions to many people. As evidence,
http://michigantoday...1/06/whales.php which was written in 2011. Why do they continue to show these pictures? The pakicetus was not an aquatic mammal, but a terrestrial one.
It was said in a Nature article that if the pakicetus was found without the skull, it would have just been thought of as an artiodactyl. So despite all the differences from whales throughout the entire body, why is the pakicetus listed in the order cetacea?
Another interesting statement in that Nature article was that the ankle bones were adapted for running. It was stated that this adaptation was "once thought to be unique in artiodactyls, but now it is clear that it also occurred in cetaceans".
Why can't they just allow this animal to be the artiodactyl that it obviously is? Well first it would be embarrassing. The very name pakicetus means "whale found in pakistan".
So despite the myriad of differences between whales and this fossil, it continues to get included as an example of whale evolution. Why?
"the arrangement of cusps on the molar teeth, a folding in a bone of the middle ear, and the positioning of the ear bones within the skull--are absent in other land mammals but a signature of later Eocene whales"
About the teeth: "Cladistic arguments have been used to link this wear pattern to aquatic predation on fish, but no functional model or modern analogue is known. Moreover, this kind of dental wear also occurs in raoellid artiodactyls. Although this dental wear probably represents a distinctive way of food processing, it does not necessarily imply aquatic life."
So....there are other artiodactyls that have this type of dental wear.

So wait a second, it's an animal that lives on the ground, it runs, it shares many characteristics all throughout it's body of land animals, and even shares teeth with other land animals, but it's a whale!
The middle ear is often cited as the best evidence for this animal being a whale. But why? It's admitted that pakicetus had ears that were poorly adapted for underwater hearing and were adapted for hearing above ground.
Notice this statement by Nature: "It is most likely that the specializations of the pakicetid middle ear are analogous to those of some subterranean mammals and are related to the reception of substrate-borne vibrations or sound when the head is in contact with the ground".
So the all-important middle-ear similarities are probably there so that the mammal can hear vibrations when its head is in contact with the ground!
The facts regarding pakicetus are that is is nothing like a whale at all. The embarrassment of calling it a whale originally, putting it in all sorts of books and articles, and allowing artists depictions to affect students for decades is too much. They stand their ground and insist that this is an ancestor of a whale.
I think this is a perfect example of the problem of evolutionists "knowing exactly where to look" and than finding exactly what they were looking for! They needed a whale link, they found a few fragements of a skull that had some similarities with whales, and they called it a missing link. Time has shown that to be a poor comparison.
Again, there is zero proof that this is a whale ancestor. Whether it is or isn't rests solely in the deductive reasoning of the people analyzing it. The truth is that this was a land mammal with teeth similar to other land mammals, and with ears specially adapted for hearing above ground.
Claiming it is a whale ancestor is not science. Surely you guys can see the difference in calling this a whale ancestor and in other forms of science. So when I say I don't buy "hook, line and sinker" into the entirety of what science tells us, that's why. Fictional drawings, faulty analysis and blatant speculation aren't science. They are science fiction.
